What is Electrolysis and galvanic corrosion?
Galvanic Corrosion is the corrosion that occurs when two dissimilar metals are used together in a structure and exposed to an electrolyte (salt water, chemical, petrol) and the less noble of the 2 metals will corrode. For example; aluminum sheet with steel fasteners on a boat. Some pairings of metals are more at risk of galvanic corrosion. Check a galvanic series or chart.
Electrolysis is the acceleration of the galvanic corrosion when electricity is introduced to the metals in question. Connected by an external electrical source, the less noble metal experiences accelerated galvanic corrosion.
while both processes involve metals and electrolytes, their dependence on an external voltage source distinguishes them.
The following has been prepared as a design guide to the economical and effective use of PLASTAZOTE foam in protective packaging. It will enable design engineers to predict the performance and design parameters of PLASTAZOTE foam cushion systems over a wide range of conditions and handling situations. Consideration is given not only to the primary concern of designing for optimum shock protection but also to other aspects of cushion design which can have a serious impact on the effectiveness of a protective packaging system.

Vibration motion consists of six modes: three linear and three rotational. Vertically applied vibration is generally considered to be the most pertinent.
PLASTAZOTE Foam: Key Features
PLASTAZOTE foam is a cross-linked closed-cell polyethylene foam manufactured using high-pressure gas technology. PLASTAZOTE foam is available in a range of densities and colours, and offers many characteristics of particular importance in protective packaging.
Inert and Lightweight
Tough, Flexible, and Resilient
Highly Energy Absorbent
Easily Fabricated or Thermoformed Using Well-Known Techniques
Wide Operating Temperature Range
Excellent Chemical and Water Resistance
Unique Advantages
The advantages offered by PLASTAZOTE foam over more traditional materials in the protective packaging of fragile high-value goods have been appreciated by designers for many years. However, PLASTAZOTE foam also offers significant advantages over other polyethylene and copolymer foams as a direct result of the manufacturing process employed.
Conductive and Antistatic Foams
PLASTAZOTE and EVAZOTE conductive and antistatic foams have been specifically developed for the packaging of static-sensitive components and goods to eliminate the risks normally associated with the use of standard foam packaging grades in static-sensitive environments. Further information on the general use of these materials is given in the brochure 'Plastazote and Evazote Antistatic and Conductive Foams' which is available on request.
